Overview
The EPRO CON021 + PR6424/002-130 is an industrial eddy current measurement system consisting of a CON021 signal converter and a PR6424/002-130 proximity probe. The system provides non-contact measurement of shaft vibration, displacement, and position in rotating machinery. Furthermore, the CON021 conditions probe signals and provides standardized analog outputs for connection to monitoring and control equipment.
Product Features
- Non-contact measurement: Uses eddy current sensing to measure shaft movement without direct mechanical contact.
- Signal conditioning: The CON021 converts the probe signal into a standardized output for monitoring equipment.
- Measurement applications: Supports monitoring of shaft vibration, axial displacement, and position.
- Probe connection: Uses a self-locking LEMO socket for the sensor input.
- Frequency response: Supports measurement signals up to 20 kHz.
- Temperature range: The converter operates from -30 to +100 deg C.

Signal Processing and Measurement
The PR6424/002-130 probe detects changes in the distance between its sensing tip and a conductive target. The CON021 processes the resulting eddy current signal and converts it into a proportional output for monitoring equipment.
Furthermore, the converter’s frequency response of 0 to 20 kHz supports dynamic measurement signals. Its rise time of less than 15 us describes the response speed, while the gain error specification indicates measurement accuracy within the stated frequency range.
Sensor Connection and Output
The CON021 accepts compatible EPRO PR6422 through PR6426 eddy-current sensors. Meanwhile, its self-locking LEMO socket provides the sensor connection.
The converter operates with a nominal -24 VDC supply and provides either -4 to -20 V or -2 to -18 V output. The required output range should be matched to the receiving monitoring equipment before installation.
